查询词典 occlusion

目的 急性心肌梗死（ acute myocardial infarction，AMI）早期最显而易见的病理解剖学现象为冠状动脉的完全闭塞，所以，既往人们的研究兴趣以及治疗策略大多集中于心外膜下的闭塞冠脉，并且已有多种成熟应用于临床的闭塞冠脉血运重建措施。

Results 520 arteries were examined in all, and DSA detected 130 normal, 390 abnormal (75.0%, 120 artherosclerosis, 201 stenosis, 69 occlusion). In the diagnosis of MRA to angiostegnosis , the sensitivity was 95.4%, the specificity was 96.2%, the false positive was 1.3%, and the false negative was 17.7%.

结果 检查缺血性脑血管患者的血管520条，DSA发现130条正常，390条异常（75.0％），其中动脉粥样硬化120处，狭窄201处，闭塞69处；MRA诊断血管狭窄的敏感性为95.4％，特异性为96.2％，假阳性为1.3％，假阴性为15.5％。

In the human body model based on the use of apar strip ie, 3' IA-body parts, and use a rigid body on the different nature of the human body to determine the end use of region matching and feature point matching the completion of many of the track, and it a better solution to the occlusion.

在人体模型的基础上，利用apar条形ie，3 IA-体的部位，并利用具有刚体性质的躯干对不同人体进行确定，最后采用区域匹配和特征点匹配完成多人的跟踪，并且很好的解决了遮挡问题。

In clinical and experimental studies, it has been found that cerebral ischemia and cerebral infarction were easy induced by hypotension in elder, hypertensive cerebral arteriolosclerosis, and stenosis or occlusion in carotid artery or in major cerbral arteries, butnow the effect machanisms still remain unclear.

从临床研究和动物实验也发现，在年老、高血压脑动脉硬化和颈动脉或大的脑动脉狭窄或闭塞时，低血压易诱发脑缺血和脑梗塞，但是目前其作用机制还未完全阐明。

If the condylar fracture is treated inappropriate, it may cause some complications, eg: limitation of mouth opening, pain in TMJs, occlusion disorder, arthrocleisis and so on. The fractural condylar can't rebuild well without treatment. For any kind of condylar fracture, treatment should strive for anatomic replacement and avoid removing the fractural residual.

研究结论：髁状突骨折如治疗不当，容易出现一些后遗症或并发症，如张口受限、关节区疼痛、咬合错乱以及关节强直等；成人髁状突骨折如不作处理，并不能自行改建形成新的功能完好的关节；所有类型的髁状突骨折，治疗时都应争取达到解剖复位，不应轻易摘除骨折残端。

CTA may prove useful in detection of carotid artery stenosis and occlusion, and provide information about calcific plague, ulceration for carotid endarterectomy.

采用电子束CT和三维工作站可清晰显示颈动脉的解剖和异常，为颈动脉内膜剥脱术提供可靠的影像学依据。

1 The approach of LVB cannulated by passed retrograde across the aortic valve can be performed easily and reduce LV pre-load and LV work, as well as cardium oxygen consumption significally; 2 This LVB can improve coronary artery perfusion and cardiac function while AOMP can be maintained after LAD occlusion; 3 There has a potential impariment effect on the right ventricular function with excessive amount BFR (over 85%) during LVB, particularly in the present of myocardial ischemia; 4 Roller pump is not suited for a prolonged bypass because of significant damage to the blood system.

由此我们得出以下实验结论：经外周动脉逆行左室置管转流方法操作简便、迅速。能明显减少左室前负荷，减少左室作功，降低心肌耗氧量；能维持严重心脏缺血后的平均动脉压，改善冠脉循环灌注和左室功能，具有临床应用的可行性。85%以上转流率对缺血心脏的心功能有潜在的损害效应。以75%左右转流率较为合适。转子泵不适宜用作长时间转流。

Stenosis of internal caroid antery was found in 32 of 48 branches in 24 case. 5 branches were occlusive and 11 branches were normal. 22 cases with large or moderate cerebral infarction volume （＞5 cm3） confirmed by CT and MRI were smaller than those on MSCTPI as having abnormal perfusion lesions,which were moderate and obvious stenosis and occlusion on MSCTA. In 2 cases with small cerebral infarction volume（＜5 cm3）, MSCTPI and MSCTA revealed normal.

其中32支颈内动脉呈不同程度的狭窄，5支颈内动脉闭塞，11支血管无狭窄。22例在常规CT及MRI图像上为中及大体积梗死（＞5 cm3）的患者，MSCTPI发现与梗死灶相对应的异常灌注区，且均比常规CT及MRI图像上病灶体积大， MSCTA显示颈内动脉呈中重度狭窄或闭塞。2例未发现明显灌注异常的患者，为小体积梗死灶（＜5 cm3），MSCTA显示颈内动脉正常。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
